the boat to a specific waypoint location, or through a
route of waypoints. The information received from the
navigator automatically changes the course to steer to
keep the boat on the track line and direct the AP24 to the
destination waypoint.
If the AP24 is connected to a navigation receiver that
does not transmit a message with bearing to next
waypoint, it will steer on Cross Track Error (XTE) only. In
that case you have to revert to AUTO mode at each
waypoint and manually change set course to equal
bearing to next waypoint and then select NAV mode
again.
To obtain satisfactory navigation steering, the following
points must be fulfilled prior to entering the NAV mode:
• The AP24 autosteering must be tested and determined
satisfactory
• The navigation receiver (GPS, chart plotter) must be
in full operating mode with adequate signal
characteristics for valid position and navigation data
• At least one waypoint must be entered and selected as
the current “Go to” waypoint
The data source when operating in NAV mode is the
Navigation (Nav) source. It is normally the same as the
Position source (GPS/chart plotter) see page 49.
Navigational steering should only be used in open waters.
When selecting NAV mode, the AP24 maintains the
current set course and prompts the user to accept the
course change towards the destination waypoint.
Press the MODE key followed by the mode softkey
to activate the NAV prompt display.
